Choose how many modules and how much load. The backup time is a guide, not a guarantee.
The same 48 V 50 Ah module in series. The string length is set by the DC bus your online UPS expects, so the pack is matched to the UPS rather than the other way round. One series string per system, no parallel strings.
The UPS is bought separately. Tell us the make, model and DC bus voltage and we will confirm the string before quoting. Backup minutes depend on the actual load, not the kVA label.
Lead-acid figures are typical industry values. Retron figures are design targets for this generation.
Send us your UPS rating and load. We will size the pack and share a quote.
